The competition heats up and takes an unexpected turn in the third episode of Andrej Lupin’s “Secrets of Prague.” The teams have been given clues to locate a particularly conspicuous modern architectural landmark in the city. Once you’ve seen it you’d never forget it, but finding it based on cryptic clues proves difficult. And when Vanessa Decker refuses to follow teammate Leila Smith’s hunch they finish last and get bounced from the competition. Angry and hurt, Smith wanders off to lick her wounds and happens to bump into a rival team — Cristal Caitlyn and Elisa. When they see how sad and disappointed Leila is they decide to try and lift her spirits, so they take her to the hotel bar and share a bottle of wine. And then they share each other.
